GASOLENE-ENGINE.

Patented Mar. 4, 1913.

Application filed June 20, 1911. Serial No. 684,351.

To all whom it may concern:

Be it known that I, DANIEL H. Mom, residing at Lincoln, county of Lancaster State of Nebraska, a citizen of the United States, have invented certain new anduse-Z ful Improvements in Gasolene-Engines; and? I do hereby declare the following to be a full, clear, and exact description of the in-% vention, such as will enable others skilled{ in the art to which it pertains to make and use the same.

My invention relates to improvements in gasolene engines.

It has for its object the placin of an air tight packing for the piston,wl1icli separates the gas of the combustion chamber from the outside air, at a mint where said packing will not be affected by the heat enerated in the combustion chambers and wifi be capable of being cooled without affecting the combustion chamber.

It also has for its object to provide means for preventing the lubricant used to lubricate the engine from being heated.

It further has for its object to cool the several parts of the engine by atmospheric air, water or other cooling medium.

It still further has for its object to 1'0- vide an engine of the character described which is simple, inexpensive, durable and com met in construction and easily operated.

The invention consists in the features and combination of features as hereinafter de scribed and claimed.

Referring to the drawingsz-Figure 1 is a top plan view in elevation. Fig. 2, a central vertical section. Fig. 3, an end view. Fig. 4, a cross-section on the line ww of Fig. 2. Fig. 5, a detail section of the piston. Fig. 6, a section of a modified form of my invention. Fig. 7, a cross-section on line y 1y of Fig. 6. Fig. 8, a section of a modified form of my invention applied to a vertical type of engine.

In the drawin s in which similar reference characters d enote corresponding parts throughout the several views, 1 indicates the outer cylinder of my engine which is preferably made in two sections 2 and 3 secured together .by means of bolts 4 passing through the flanges 5 of each section.

Theleft hand end of theouter cylinder 1 is provided with a flange 6 to which is secured by means of bolts 7 a cylinder head 8 having an inlet pipe 9 and an exhaust pipe 10 therein and a smirking device 11, while the o posite or right hand end of the outer cylin er 8 is provided with a flange 12.

13 indicates the inner cylinder spaced apart from the outer cylinder by havmg a space 14 between the inner surface of the outer cylinder and the outer surface of the inner cylinder, the inner cylinder being preferably made in two sections 15 and 16 having flanges 17 secured together by means 0t bolts 18, and being 0 on to the air at its outer end 19 and having a flange 20 at its outer end which is secured to the flange 12 on the adjacent end of the outer cylinder by means of bolts' 21, and said inner cylinder 13 having a cylinder head 22 at its inner end with inlet pipe 23, exhaust pipe 24, sparking device 25 and a central sleeve 26 supported within said cylinder by means of a depending bracket 27.

The piston 28 is provided with a piston head 29, having a iston rod 30, which passes through the s eeve 26 of-the inner cylinder 13 and packing box 26, and a flange 31, said flange 31 being slidably mounted in the space 14 between the outer and inner cylinders so as to fit closely therein and adapted to be lubricated by oil or other lubricant in any desired manner. An explosion chamber 33 is formed between the cy inder head 8 of the outer cylinder 1 and an explosion chamber 34 is formcd'in the interior of the piston, between the iston head 29 and the cylinder head 22 of tie inner cylinder 13.

All the joints will be made air tight by means of any suitable well known packing material 35, except the joints at the points 35, between the piston ilange and the inner and outer cylinders, which joints will be rendered absolutely air tight by means of spring packing rings 35 seated in roovcs in rings 35 and suitable soft packing 35 on either side of said rings 35. The above joints may, if desired, be made air tight by any other means.

It will be noted that by placing the air tight paokin which consists of packing rings 35 at't e point 35, remote from the BEST AVAILABLE con combustion chambers, they dWill 1123 bp affected y the'hest gencrate imsa v c 1a bers-aiidat tli same timean b dooled 1 any desired manner Without aflectm" the temperature of the saidicombustion c 1am:

The inlet and exhaust ipes of the=inner 1 and outer cylinders will e provided with suitable valvesanotvshofivn- 1-.

The piston flange is pre ferably made, o t light thin steel, but of course may be made of any, suitable material, and as said before is dcsigii'e'df to ffit closely in space 14; but not so pro-say as to (prevent:

the air at all times and as the inner "sii rface of the 1am; cylinder and'tlie sleeve 'are exshown in Fig. 6, the outercylinder isind i cated at 36 and is provided with a cylinder licad BTat one end having inlet 'and exhaust pipes and afframework 38 at the oppos te end. The inner cylinder 39 which is spaced apart from the outer cylind'er'by me'ans of a s ace 40, is open to the air at its outer end an also connected to theframevorlrlfifi and its inner end is provided 'withinlet and exhaust pipcs. y v. 1 The piston il is provided vitha piston rod 42, piston head 43 and afiange 44, said flange being slidably mounted in the s ace l0 between the cylinders 86 and 39 an designed to be projected beyond the ends of the said cylinders andcoolcd by the air. at each'strolreofthe piston., Inl i 8 ,'a 'n'io difi'ed form of. my invention is diownfappliedtoa vertical ty e of engine,"in which all the parts .are simil iir to the pa1'ts "sh'oivn in Eighfi except that the piston rod extends upward from the piston and a receptacleao '11s providedwithm the framework t-lS'for coritainin" wateror other cooling medium into which ,theflan e of the piston is adapted to be projecte and cooled at each stroke of the piston.

It will be scen that by ,myinvention the several parts maybe kept cool ,by air, water, or any other suitable cooling medium.-
